ELECTRIC HEATER.

"Be it known that LEDWIN R; WATER'MAN I a citizen of the United States,.and residing at San Francisco, in thecounty of San Francisco and-State'of California, have invented certain new and usefullrnprovements in Electric Heaters; and I do hereby declare that the following is a fulh'clear, and exact description of said invention, such as will enable others skilled in theart to which it most nearlf appertains to make, use, and practice the same.

-' 1 My invention relates toth'at class of devices which are especially constructed for the purpose of heating. instantaneously liquids y electric means, and .eonsists particularly in the arrangement or combination of its varesult, as will rious parts cooppratingto-obtain the desired e'hereinafter more particularly described,'and pointed out in the claims.

A The objectofi my invention is to simplify theconstruction of that class of devices and be desired.

at the same time-increase their effectiveness,

.. and, furthermorewhich can be used with either a direct or alternating current, as may A further object, I have in'view is to pro vide means .to increase the heating-surface,

' which like letters of reference made use of in the drawing indicate like parts wherever emshapeto present a neat appearance. Secured centrally within the casing is .a recepwhereby a larger body of running hot water can be obtained instantaneously and keep it at comparative degree of heat for some time, after its sources of supply are cut off.

A still further obj ect of my invention is to provide meansjwherewith the same can be easily and quickly connected to an incandescent-lamp socket and liquid-s11 ply or water? faucet and disconnected for the purp se of carrying awayits contents when desired.

Referring to the herewith-annexed draw. in? consisting of one figure, a central vertioa sectional view is shown of the invention which forms apart of this specification, in.

ployed.

A represents the outer shell or casing of 5 my invention, which is provided with bot.-

tom B, removably secured thereon for the I purpose of repairing oradiusting, when dorriaterial and of a'convenient and ornamental Specification of Letters Patent. A plication filed retrtar isnaoi. Serial No. 193,762;

tom and similar chamber E above its top,

and the lower end of the receptaclehisl prlpet, w ie t e vided with aninlet and an out upper end has a vent for safety and other objects which will be mentioned hereafter. Within the receptacle the desired liquid brought therein is heated by electric means;

adjustably secured around its outercircumference. v

The inlet previously mentioned'consists ofpipe F, which is proyided with stop-cock a, conveniently secured at suitable lacethereon, and may be connected eit er permanently or temporarily to the source of liquidsupply, as desired, or'to a yvater-faucet by: means of rubber hose, as'shown in the draw ing, and its outlet consists of pipe :G, which is provided with faucet b. Both the-inlet and outlet pipes are secured within the chamber l) to the bottom of the receptacle by meansv of a T and connecting-fittings 0.; -Thus in this manner I provide onejadjustmentonly to thereceptacle. t by The vent previously mentioned consists of pipe H, secured within the chamber E to the top part of the receptacle and projecting outwardly through the-casing and downwardly along its side and curved outwardly for con venient purposes. This vent, aside of being for safety purposes, as DILVlOltSlf. mentioned,

serves also as a regulator to indicate that the receptacle is full or as an outlet when acontinuous running strcan'i fiflltfltttl liquid is desired.

By the above-describcd arrangement, re-

latingparticularl to the inlcta-nd butlet and I the vent, it will be readily' conceived that I' am able to draw through the faucet b the liquid directly from its source of supply and at the sameti-mc retain within the receptacle the liquid 'Illt'lLlRztf. be contained therein bf. plugging the vent-orifice and by the same means to draw the heated liquid from the rc-' ceptacle l) turning oll tlu-stop-coel u. of the inlet-pipe F and returning the plugfrom the vent-ounce, which may have been placed thereon for the purpose p'st. mentioned! The electric, means adjustably secured around the circumference of the'rcceptacle, s red, the various parts placed therein. The casing'ls preferably madeof thin metallic I of layers of suitable material, around which taclelC,which is 'placed'in such a manner' resistance-wires (Z are." wound in-coils or to form; the hotair chamber below -its botspiral-like manner. These cores are placed independently -one above the other in a vertical line if used in pluralitv and are adapted to be rernoved from their position when desired for the purpose of replacing or r cpairing them. I The ends of the wire (Z just mentionedflproject into the hot-air chanabcr E, formed above the top part of the recepvidedwith an incandescent lamp J, which is when thecurrent'is applied to my invention v fact, thus serving asan indicator.

connected to-the power-Wireby 1r cans of connecting ends 71.. Arranged in this manner,

the light from-the lamp will indicate that The cas-- ing is providedwithsuitable packing K, in-

'terposed between its side and the cores, and

alsotheto part of .the receptacle is sire-i: larly rovi' ed, the object of which and the chain ers D andE'is to provide suitable means around the receptacle for the purpose of retain'ingthe heat therein.

With inj invention if' desired to. keep the liquid at a desired or uniform degree of ternperature-forvarious purposes I place arheostat or similardevicein the circuit,

regplating the current passing therein.

elieving I have made novel and useful improvements in that class of electric heat- I mg devices and-produce a simple and con vement means whereby liquidc'an be 1n'sta-n -heat-generat1ng device secured around said taneously heated to a desired degree of ten;- perature andl. havin described the same,
